Flocculation

Flocculation in the field of chemistry is a process in which colloids come out of suspension in the form of floc or flake either spontaneously or due to the addition of a clarifying agent The action differs from precipitation in that prior to flocculation colloids are merely suspended in a liquid and not actually dissolved in a solution Get price
